Things you don't cheap out on
There are somethings I'm willing to cheap out on, my fiance hates that I buy a lot of my clothes at Old Navy, but there a some things I'm willing to spend the extra money on for high quality.
For me that is beer and eyeglasses.
I can talk about beer quality all night, but with glasses it's likely because I had no health coverage for eyeglasses and I simply couldn't afford to buy new one's. I had my first pair of glasses from 6th grade to my senior year of high school. They were beat up to hell, I wore them under my football helmet, I wore them to concerts with mosh pits. They had electric tape holding them together for a few years.
